A motor 5 is fixedly installed on the outer wall of one side of the base 1, and the rotating shaft of the motor 5 and one end of the screw rod 4 are coaxially fixed.

[0025] Driven by motor 5, one end of the material guide frame 802 is just above the external feeding port, and the motor 5 is started. The motor 5 drives the screw rod 4 to rotate in the installation groove 2. The bottom plate 3 restricted by the installation groove 2 will be driven by the screw rod 4 to slide to one side, and then the spiral feeder 702 and the material guide frame 802 at one end thereof will also move synchronously. For feeding, it is only necessary to store the materials in the storage hopper 703, and then start the spiral feeder 702. The materials in the storage hopper 703 can be slowly conveyed to the upper position by the spiral feeder 702, thereby achieving the purpose of continuous feeding.

[0026] like Figure 2 and Figure 4 As shown, an adaptation component 8 is installed at one end of the top of the screw feeder 702, and the adaptation component 8 includes two extension frames 801 fixedly connected at both ends of the circumferential outer wall of the screw feeder 702, and the same material guide frame 802 is rotatably connected between the two extension frames 801, and the material guide frame 802 is located below the discharge port of the screw feeder 702. A vertically arranged limiting groove 804 is opened on the outer wall at one end of one of the extension frames 801, and a rack 805 is slidably connected in the limiting groove 804.
